AbstractThe etiology of childhood obesity and the associated morbidity is multifactorial. Recently, data suggesting a prenatal programming towards later childhood obesity and metabolic deregulation through the intrauterine environment has emerged. This study explored the concentrations of adipokines and their mutual relationship at birth in children born to non-diabetic mothers.Adiponectin, leptin and sOB-R were measured using ELISA-based commercial kits in umbilical cord blood from 60 neonates (30 born large for gestational age [LGA] and 30 born appropriate for gestational age [AGA]). Children exposed to maternal diabetes, chronic disease and preeclampsia were excluded.The LGA group exhibited significantly elevated concentrations of leptin (p<0.001) and of free leptin index (p<0.001) and decreased sOB-R concentrations (p=0.005) when compared to the AGA group, which persisted in multiple regression analysis after taking the gestational age into account (p=0.048, p<0.001 and p<0.001, respectively). Only a trend towards a difference in adiponectin was demonstrated (p=0.057) regardless of adjustment (p=0.150). However, the leptin/adiponectin ratio was elevated in the LGA group (p=0.008), regardless of adjustment (p=0.039).The data indicate a disturbance of adipokines in macrosomic newborns and that the mutual ratios between adipokines may provide a more sensitive marker of metabolic disturbance than any isolated adipokine.

Objective Herein, we measured the concentration of insulinlike growth factor I (IGF-I), IGF-II, leptin, adiponectin, ghrelin, resistin, and visfatin in the umbilical cord blood of newborns categorized as “small for gestational age” (SGA), “appropriate for gestational age” (AGA), and “large for gestational age” (LGA). Our aim was to elucidate the link between the levels of these proteins and fetal growth. Study Design A total of 96 term infants were included and categorized into three weight categories. Their venous cord blood samples were collected to measure the levels of IGF-I, IGF-II, leptin, adiponectin, ghrelin, resistin, and visfatin. Results IGF-I, visfatin, and leptin levels showed significant differences among the groups. Pairwise comparisons showed that adiponectin (p = 0.023), resistin (p = 0.025), and ghrelin (p = 0.005) levels were significantly lower in the SGA group than in the LGA group. Correlation analyses showed a strong association of IGF-1, IGF-II, and leptin levels with birth weight (r = 0.644, p < 0.001; r = 0.441, p < 0.001; and r = 0.404, p < 0.001, respectively). Conclusion SGA newborns showed a significantly higher visfatin concentration and lower ghrelin, leptin, resistin, and adiponectin levels than the AGA and LGA newborns did.

Objectives: Premature birth, defined as less than 37 weeks gestation, affects approximately 12% of all live births around the world. Advances in neonatal care have resulted in the increased survival of infants born prematurely. Although prematurity is a known risk factor for different cardiovascular diseases, little is known about the pathophysiology of vasculature during premature gestation and angiopoietic factors network during premature birth. Aims: The objective of this study was to determine whether the profile of several pro-angiogenic and anti-angiogenic factors in umbilical cord blood (UCB) is different in healthy appropriate-for-gestational-age preterm newborns and normal term babies. The second aim of this study was to investigate the microRNA (miRNAs) expression profile in UCB from preterm labor and to detect miRNAs potentially taking part in control of angogenesis-related processes (Angio-MiRs). Methods: Using an immunobead Luminex assay, we simultaneously measured the concentration of Angiogenin, Angiopoietin-1, FGF-acidic, FGF-basic, PDGF-aa, PlGF, VEGF, VEGF-D, Endostatin, Thrombospondin-2, NGF, BDNF, GDNF, and NT-4 in UCB samples collected from the preterm (n = 27) and term (n = 52) delivery. In addition, the global microRNA expression in peripheral blood mononuclear cells (PBMCs) circulating in such UCB samples was examined in this study using microarray MiRNA technique. Results: The concentrations of five from eight measured pro-angiogenic factors (VEGF, Angiopoietin-1, PDGF-AA, FGF-a, and FGF-b) were significantly lower in UCB from preterm newborns. On the contrary, two angiostatic factors (Endostatin and Thrombospondin-2) were significantly up-regulated in preterm UCB. Among analyzed neurotrophins in preterm newborns, the elevated UCB concentration was found only in the case of GDNF, whereas BDNF was significantly reduced. Moreover, two angiopoietic factors, VEGF-D and PlGF, and two neurotrophins, NT4 and NGF, did not differ in concentration in preterm and term babies. We also discovered that among the significantly down-regulated miRNAs, there were several classical Angio-MiRs (inter alia MiR-125, MiR-126, MiR-145, MiR-150, or MiR155), which are involved in angiogenesis regulation in newborn after preterm delivery. Conclusions: This is the first report of simultaneous measurements of several angiopoietic factors in UCB collected from infants during preterm and term labor. Here, we observed that several pro-angiogenic factors were at lower concentration in UCB collected from preterm newborns than term babies. In contrast, the two measured angiostatic factors, Endostatin and Thrombospondin-2, were significantly higher in UCB from preterm babies. This can suggest that distinct pathophysiological contributions from differentially expressed various angiopoietic factors may determine the clinical outcomes after preterm birth. Especially, our angiogenesis-related molecules analysis indicates that preterm birth of healthy, appropriate-for-gestational-age newborns is an “anti-angiogenic state” that may provide an increased risk for improper development and function of cardiovascular system in the adulthood. This work also contributes to a better understanding of the role of miRNAs potentially involved in angiogenesis control in preterm newborns.

In recent years, a number of the studies of myokine irisin in adults and isolated in newborns have been carried out. The role of adipocytokines in the growth and development of the fetus and children has been shown.The aim of the study was to assess the levels of myokine irisin and adipocytokines in newborns small for gestational age at birth and to analyze the relationship between the parameters of the hormonal status of children and their mothers.49 newborns and their mothers were examined. Two groups were identified: group 1 (Gr1) – newborns small for gestational age (n = 24), group 2 (Gr2) – newborns appropriate for gestational age (n = 25). The levels of irisin and adipocytokines in the blood serum were determined by the enzyme immunoassay.Newborns small for gestational age had significantly lower levels of leptin and IGF-1 in the umbilical cord blood compared to children with physical development corresponding to the gestational age. There were no significant differences in the irisin content of cord blood serum in newborn Gr1 compared with Gr2. The presence of significant positive correlations between the level of irisin in the umbilical cord blood of newborns small for gestational age and the body weight at birth was established. In Gr1, a positive relationship was found between the irisin levels of mothers and newborns (r = 0.518, p = 0.028). The differences in the irisin content between the groups were established, taking into account the delivery mode (p = 0.0104).The revealed statistically significant differences in the concentrations of the analyzed metabolic markers in mother–child pairs, their relationship with clinical and anthropometric parameters substantiate the possibility of using irisin and adipocytokines as predictors in predicting the formation of metabolic disorders of infants small for gestational age.
